THE COAL OCCURRENCE TECTONIC UNITS AND COAL CONTROLLING CHARACTERISTICS in NORTHWEST CHINA

摘要：

　　The coalfield sructure is mainly influenced by the Tethyan Geodynamics system and ancient Asia Geodynamics system in the northwest region, but theres no unified understanding for the coal occurrence tectonic unit yet.Based on the characteristics of coal-bearing strata of the northwest region, the northwest coal occurrence tectonic unit is divided into three systems: the northwest coal occurrence tectonic region, 3 coal occurrence tectonic sub-regions, 16 coal occurrence tectonic belts (points).Based on geodynamics theory and coal-controlling characteristics as the leading clue, this paper explores the basic coal-controlling characteristics in the sub-regions, and studies on the sructure characteristics of the Tianshan Orogen and the Qilian Orogen that impact the coal measure deformation.To carry out a study of the northwest region coal occurrence tectonic units, is of great significance for the evaluation and exploration of coal resources.
